The objective of this work was to analyze land use dynamics in the Brazilian Cerrado region from 2002 to 2013. This analysis was based on the interpretation of Landsat satellite images carried out by the projects Projeto de Conservação e Utilização Sustentável da Diversidade Biológica Brasileira (Probio) and TerraClass Cerrado 2013, both coordinated by Ministério do Meio Ambiente. In 2002, 38.9% of the Cerrado was covered by some type of anthropic activity. In 2013, this percentage increased to 43.4%. One of the main highlights is the emergence of a new agricultural frontier in the northern region of the study area, known as Matopiba.
The Table Tennis game does not involve large displacements by the practitioner in the environment, a characteristic that can promote greater safety for the elderly in locomotor terms. In addition, it needs coordination, agility, speed of reaction, dynamic balance, which have been the focus of current recommendations of physical activity for the health of adults and the elderly. The aim of this study is to investigate the effects of table tennis practice on physical and functional fitness in the elderly. This quasi-experimental research with a parallel and controlled design. The sample consisted of 16 elderly people, allocated 8 in the experimental group (EG) and 8 in the control group (CG). The research lasted 18 weeks, with 2 weeks of evaluation (initial and final) and 16 weeks of intervention. Physical fitness assessments were carried out using the agility and balance and functional fitness tests. In the intra-group comparison (pre-post intervention), EG showed a significant difference for the variable agility (pre: 15.6 ± 1.2 s; post: 14.7 ± 0.7 s). Also, the EG showed a reduction in Area (pre: 11.00±3.32 cm2; post: 6.52±3.06 cm2), AP Amplitude (pre: 4.92±2.77 cm; post: 3.28±0.58 cm) and ML speed (pre: 2.77±1.07 cm/s; post: 2.31±1.03 cm/s) in the Tandem posture with eyes open. Our findings highlight the importance of a Table Tennis program, administered twice a week and consisted of low to moderate intensity activities, to promote a beneficial effect on the agility and balance of physically active elderly people.
RESUMO:O presente trabalho visa ressaltar a importância dos estudos em bacias hidrográficas como unidade de estudo físico-paisagísticos compostas por elementos interdependentes capazes de serem mensurados e zoneados. Na bacia do córrego Bom Jardim localizada dentro dos limites municipais de Brasilândia/MS, ocorrem diversos tipos de processos erosivos tanto de âmbito laminar quanto linear que por sua vez transportam sedimentos das vertentes da bacia para o leito de seu canal principal e seus afluentes. Nesse sentido objetivou-se demonstrar a importância da compreensão dos fatores físicos principais constituintes em uma bacia a fim de compará-los e correlacioná-los obtendo assim de forma adaptada os níveis de Fragilidade Potencial e Ambiental ao qual a mesma está sujeita. Faz-se necessário, portanto uma análise sintetizada dos dados advindos de mapeamentos temáticos de Declividade, Solos, Geologia, Pluviometria e áreas especiais denominadas aqui de Áreas de Prioridade Biológica de conservação para uma melhor compreensão da evolução dos diferentes processos geológico-geomorfológicos averiguados na bacia e que afetam a mesma deixando-a com baixos e/ou altos níveis de vulnerabilidade ou fragilidade. O produto final da sintetização desses dados pode servir de base para a construção de um planejamento ou plano de manejo que identifique os processos que afetam o meio físico natural da bacia como um todo.
